- •
Variation in salinity in soil in the Yangtze delta was analysed geostatistically.
- •
Strong lateral and vertical trends and covariances of the residuals were estimated by REML.
- •
The anisotropy could be represented by a non-affine transformation.
- •
Space–time covariance functions led to satisfactory fitting.
- •
Kriged predictions were mapped as three-dimensional charts.
